While Godowski was examining me, Craig managed to get out his microscope and was looking through it at the strange black specks on the paper.  There, under the lens, he could see the most remarkable, almost microscopic creature, all legs and feelers, a most vicious object.

Weak though he was, he could not help an exclamation of exultation at his discovery, just as Godowski had finished with me.

“Look!” he cried, calling the doctor.  “I know what the trouble is, Godowski.”

He had started to tell, but the excitement of the journey and the exertion were so great that he could hardly mumble.

“Here—­look—­on this paper,” he cried.  “From the telephone—­”

He had risen and was handing the paper to the scientist when his weakness overcame him.  He fell flat on his face on the floor and dropped the paper, spilling the contents.

Godowski, now thoroughly alarmed, bent over Craig.  But the delirium had overcome Kennedy, too.

Unable to make any sense out of Craig’s broken wanderings, Godowski lost no time in taking samples of our blood.

Then he hurried away to his laboratory in his car.  As he did so, however, Long Sin leaped into a taxicab which was waiting and followed.

. . . . . . .

In Godowski’s laboratory, where he was studying tropical diseases, the bacteriologist set to work at once to confirm his own growing suspicions.

From a monkey which he had there for experimental purposes, he drew off some blood samples.  Then, with the aid of his assistant, he took the blood samples he had obtained from us.  The monkey’s blood, under the microscope, seemed full of rather elongated wriggling germs of a peculiar species.  In and out they made their way among the blood corpuscles each like a dart aimed at life itself.

Then he took the samples of our blood.  In them were the same germs—­carried by that gruesome tick!

“The spirillum!” he muttered.  “They are infected with African recurrent fever.  The only remedy is atoxyl, administered intravenously, after the manner of Professor Ehrlich’s famous ’606’.”

Godowski had rung the call box hastily for a messenger, when Long Sin, who had managed stealthily to creep up to the doctor’s laboratory window, scowled, through at the action—­then moved away.

While his assistant gathered the apparatus, the doctor wrote: 

Miss Anne Septix, 301 W.—­th St.

Please go at once to the apartment of Craig Kennedy,—­Claremont
Ave.  Surgical case.

Godowski, M. D.

The boy arrived finally and the doctor gave him a generous tip to hurry with the note.

He had not turned the corner, however, when Long Sin appeared.  Subtly he played on the boy’s cupidity to get him to deliver a note of his own, even offered to deliver the boy’s note for him.  The flash of a five dollar bill made the rest easy.
